I have never had cats but I know when Dudley and Kayla play tug a war, I was afraid she was going to break his neck. He is tiny and she out weighs him about 4lbs. I know it can be scary but if it would put your mind at ease I would seperate them when you were not home. Just close your yorkie off where the cats won't be around him until you are able to referee. I think in time they will get use to each other. It just takes time and patience. Good luck. |
